ness and various efforts have been made to overcome this defect; I havefound that if rolledstock, preferably a round bar, which gives strength vwith lightness, is bent into bracket form and set into theheader itself instead of merely straddling. it the joist will not sag and the strength of the floor is greatly increased. I attribute fthisto the bracket within the header is supported on all sides instead of being. free to bend in one direction when theload comes on it. 1

In the drawings 1 is thejoist. lVhile I use and joist herein :1.

the header and 2 is the terms header do not limit myself thereto as my improved. buildingconstructo v I another for load carrying tion may be used an angle to one purposes.

The bracket consists essentially of a bot tom bar approximately the width of the joist ,to be varied, s de. bars between which the joist is adapted to lie, top bars lying on ten O the header 1 and hookedlends entering face of the header, or,

the topbars enter directly into apertures n the side of the header, he hooked ends being omitted. i

My preferred, form of hanger is 'sho wn .in

Fig. 1 in which the side bars .lz l K are in the alternative straight down between 19 and 20 to lie against the header l and areibent forward at 20 tQ glVQ additional hearing to the joist 2. Tests have shown that. the hanger stretches down from the P911). 19 to the point 22 and bearing plate; lfiig. 10 a side view of my i that the load has a tendency to .ra se the hooked. in portioir side, arms arestraight from to 2 2. but the produces a sguare. pull prevents the readily as it the form of side bars shown in Figs. 3 to 161' MA, further advantage .resultin-g ihooked part 1'? pulling out as hanger, the arm -can I be rested against. ;the side of theheader and the holes marked for accurately boring the holes to receive it as the sides of. the hanger between .19. and 20 will act as guides. If spike ends are used Fig. 6; the parts between .19 guides andcan be held tightly header facewhile the spikes and 20 act as against the I are driven down i into the header.

. Th bann from the 1 forward bend at 20 is that in positioning the shown in. also has the in any two timbers at of .the h anger 17 if the under side of the bottom bar 3 of the bracket to prevent the of the plate.

also extend under 12-12 are secured to both the bent side arms and has advantages in strength over the straight form as the arms of the hanger line up part way against the face of the header thereby reducing the tendency of the part'16 to pull out of its bushing or socket as the straight downward pull exerted between the points 19 and 20" eliminates the outward pull. The face of the header also acts as a' guide for the straight part of the arm from 19 to 20 and controls the position of the hanger.

As before stated the header 1 is counterbored in its top face to receive the hooks 6+6 and the top bars 5-5 rest on a bearing plate '7 secured to the upper face of the header to prevent cutting of the wood and to distribute the load. In Figs. 3 and 4 I have shown a metal bearing plate 8 set into the joist to contact with the bottom bar cutting into the joist and another bearing plate 9 against the lower part of the side of the header to contact with the i the joist to prevent its cutting into the header.

lower corner of In the structure are set into metal tures to prevent enlargement of the holes in the header. g

In Fig. 6 I haveshown a modified form of bracket in which the ends of the hooks 6 6 are spikes to enable them to be driven into'the header and the sides and bottom of Fig. 5 the hooks 6 6 bar of the round bar stock are forged into flat faces to receive the joist. I

In Figs. 7 8 and 9 I have shown how the bottom bearing plate 8 may be in the form of a piece of rolled channel section metal, in the channel of which the bottom bar sits. In Fig. 7 this is shown below the joist and in Fig. 8 as inset into the joist. In Fig. 9 I have shown how the ends of the bottom bearing plate may be notched to receive the side bars of thebracket to prevent slipping In the form'shownin' Figs. 10 and 11 the bottom plates 12-12 lie under and extend are notched to receive the hanger sides and the header. These plates header and them more solidly together.

In the form shown in Figs. 12 and 13 the bottom plate 13 is punched from sheet stock and has a V-notch at one end and a j oist' to anchor corresponding V- oint at the other end and is used to join up the joist and header. v In plate a minimum of sheet. i i

In the form shown in Figs. 14, 15 and 16 the hanger is let into the face of the header instead of the top. That face of the header is apertured and half-circle metal bushings bushings 10, in the aperl 1. Building "header apertured in its upper 'the counterbores in the header.

The essential features of my invention reside in inserting the hooks or their equivalent fastening means into the body of the header instead of merely straddling it and in providing metal bearing plates at points likelyto be cut into under load'which would allow the joists to sag. Also the forward bend in the side armsintermediate their material can be procured lengths to geta solid bearing against the face of the header and allow the bottonf bar to engage the under face of the joist at a distance from its end.
